By Jhoo Dong-chanCommercial banks are expected to conduct a major reshuffle for executives by the end of this year. Of 87 executives in the nation's big four lenders, contracts of 67 executives are set to expire at the end of this year.According to the four banks' biannual report submitted to the Financial Supervisory Service, Wednesday, the 67 executives are scheduled to complete their terms by the end of this year.Of KB Kookmin Bank's 18 executives, a total of 16, including KB Kookmin Bank Wealth Management Vice President Park Jeong-rim, will end their terms on Dec. 31. Park served the post for five years. KB Kookmin Bank sought stabilization over change in its previous reshuffling in 2017, but is expected to carry out large-scale reshuffle this year as CEO Hur Yin faces the second year into his term. Of its 21 Shinhan Bank executives, 13 are subject to be changed as their contracts expire at the end of the year. The list includes Shinhan Bank Global Investment Bank Group head Lee Dong-hwan, corporate department chief Choi Byung-hwa and Loan Group head Lee Ki-joon. Unlike KB Kookmin Bank, however, the lender isn't likely to conduct a massive change in its executive personnel as Shinhan Financial Group Chairman Cho Yong-byoung was recently indicted for unfair hiring. The group is the bank's parent company. Also, Woori Bank isn't likely to carry out a major reshuffle this year as it already conducted a thorough shake-up immediately after incumbent CEO Sohn Tae-seung came to the office last December.Of KEB Hana Bank's 26 executives, 25, except KEB Hana Bank Risk Management Group Vice President Hwang Hyo-sang, are slated to finish their terms by the end of this year.This will be the first reshuffle since Hana Financial Group Chairman Kim Jung-tae has been appointed to serve his third term in the post, so market observers expect the lender is likely to conduct a major reshuffle. "It is a common practice that a bank executive serves two years plus one," said a KB Kookmin Bank worker."The big four lenders posted record high net profit this year thanks to surging earnings in household loan sector. However, they are unlikely to maintain such earnings next year due to the new loan regulation. In order to cope with the change, they could carry out a big shake-up."
